[SOLVED] Formula for average force? In a ballistics test at the police department, Officer Rios fires a 6.0 g bullet at 350 m/s into a container that stops it in 1.8 ms. What is the average force that stops the bullet? can anyone help me to do this? or just give me the formula? The teacher gave us the right answer and it's -1.2 x 10^3N
This is just an impulse-momentum theorem problem. Impulse = Change in momentum. Impulse is F*delta t (t=time of impact) and change in momentum is just final momentum - initial momentum. Good luck
delta p= J and J= F(delta t) so delta p=6.0g(350m/s) delta p=2100 2100/1.8=1166.6666667 is that the same thing as 1.2x10^3?
